[android-developers] When to close database in ContentProvider
I am trying to write a ContentProvider which itself is based on a
SqlLite database. I am puzzled when I need to close the database
because ContentProvider has onCreate( ) function but not onDestroy( )
function.
I downloaded the android source code tree, and found
com.example.codelab.rssexample.RssContentProvider
It appears this class called openDatabase but never close on it:
=
@Override
public boolean onCreate() {
...
final Context con = getContext();
try{
mDb = mDbHelper.openDatabase(getContext(), DATABASE_NAME,
null, DB_V
ERSION);
...
}
=
mDb.close( ) is never called
=
If there is no onDestroy() from ContentProvider and we don't call close
( ) on databases, doesn't this lead to some kind of memory/resource
leak?

Lots and lots of them aren't XML at all. Atom 1.0 is better, but lots of feeds aren't Atom. Once somebody ports either Jython or JRuby and gets it really running, the problem is solved because you can use the excellent Feedparser library, which Just Works on any imaginable feed. In the interim, you might want to consider John Cowan's excellent TagSoup, which handles what its name suggests. Libxml2 also has a forgiving parser but I don't know if there's a Java interface to that. -T . Some feeds, for example CNN Money Top Stories, have embedded some characters in their content, I.e. the copyright symbol. Well, that's not valid XML and the SAXParser fails with an exception invalid token. The only help I have seen given is to fix the XML at the source and that's not an option obviously. So, I can think of 2 options and they both stink: (a) read the content first, scrub it, and then pass it to the parser. (B) use DOM instead of SAX. What I *want* to do is make the parser a little more forgiving and just accept or discard/ignore the bad text. I'm not have any luck with setErrorHandler. My error handler does not get called.

There is some seriously weird shit in RSS feeds out there. Not just wonky characters. The reason is that most blog authoring systems let you grab arbitrary claims-to-be-html off the web and drop it into your blog, so it ends up in your feed, and even with the double-escaping voodoo you see in RSS, the poison remains. As an interim step, you could simply take Atom when there's a choice of feeds, and refuse to process bad RSS. The proportion of feeds that have Atom alternatives available is pretty high. The reason this works is that one or two of the leading feed-readers decided to use real persnickety XML parsers for Atom, so the publishing industry has done the necessary whatevers to make sure they're clean. The *right* answer is FeedParser, sigh. -Tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

non-technical users do not use linux, whereas non-technical users do buy G1 phones Android, and hence the G1 is Linux based, therefore that statement can't be true.

Some users will get high value, and some will get fairly low value. You have to look at the demand curve and figure out which customers to leave out and still make good returns. If you sell something for $1 then you have to get many more customers to break even: so may be worth pricing higher and leave out customers.

[android-developers] Re: Dev Phone and RC33 update
Jon, I think we're going to have to agree to disagree. As I see it you're not willing to factor in the difficulty level in cracking the system and implementing a generic method as a differentiating factor between the protection methods, whereas my viewpoint is based on the level of effort needed to break the AndAppStore licensing system being sufficiently high to ensure that it's not worth doing (part of the reason the source code for licensing checks is available from http://andappstore.com/AndroidPhoneApplications/licensing.jsp is so that developers can vary how it's included in their code and thus eliminate the possibility of attackers scanning for a constant class name or byte code pattern). Thanks for putting the effort in to continue the conversation to this point. Al.

I'm not aware of one either, but I expect that a tool would emerge very quickly if the AndAppStore takes off when it starts being distributed with handsets and such. You could then tweak the system to stop the tool from working, but then the attacker would release a new version, and you'd be in an arms race. The reason why I say they're equivalent is that while the steps along the way may be different, the end result is the same: people who don't want to pay will get the apps for free. In my opinion adding extra hurdles just wastes the developers' time and provides a juicier intellectual challenge for those who are inclined to try to defeat the system. -- Jon -- * Written an Android App? - List it at http://andappstore.com/ * == Funky Android Limited is registered in England Wales with the company number 6741909.

[android-developers] Re: Alarms get lost when upgrading an application
I noticed the same thing. I looked at the AlarmManger code and it stores its data in in-memory arrays that are not persisted (nor publicly accessible) , even more the pending intents that the AlarmManager refers to are also lost when the device is restarted or the application is uninstalled. (This is actually what happens when you uninstall - it is the pending intent that gets lost not the AlarmManager registration). It appears that the only way to deal with pending alarms is to reschedule them. What I did in my application is to register for 3 global events - in my case Intent.ACTION_TIME_CHANGED (which occurs when the phone time gets updated to some value manually or by syncing with the cell tower), Intent.ACTION_TIMEZONE_CHANGED, and Intent.ACTION_BOOT_COMPLETED. In response to any of the those events I remove all pending alarms and reschedule them again reading the schedules from my own storage. This takes care of the device reboots and when the time zone changes (for example the user takes a plane from one time zone to another). As it turns out if your device is set to auto sync its time from the cell tower (which is the default setting) the autosync occurs many times during the day (my guess is when switching from cell towers to another). Responses to the ACTION_TIME_CHANGED will restore the schedule. This is not an ideal solution but it is good enough for my case. (The AlarmClock application that comes with the Android Source uses a similar approach) Stefan On Feb 28, 10:58 am, Mariano Kamp mariano.k...@gmail.com wrote: Hi, as far as I see scheduled alarms are lost when upgrading an application. As this seems to be an un-install and re-install I can understand what. What is the best way to cope with that? When an application is upgraded it doesn't need to be launched by the user, so it is not the most sensible approach to use the onCreate method of the launcher activity. Is there any other life-cycle event I can tap into? If that is not the case, then I would think a not-too-bad-way of handling this is to hook into the onCreate method on my launch activity, an create a PendingIntent with the NO_CREATE [1] flag and schedule it again with the AlarmManager. That shouldn't result in any change to the existing schedule, if it exists, and should create the schedule when the application is installed for the first time or after an upgrade. It's not elegant, as it expects the user to open the app after upgrading. It's not a major PITA today as the current Market expects the user to upgrade each app by hand and it is not unlikely that the user starts it, but for the future I would expect that the Market makes automatic mass-upgrades possible. Also it is not too nice to handle this logic in the UI. Furthermore it doesn't seem elegant to bother the AlarmManager with a new PendingIntent every time the app is launched. Is there anyway to query the AlarmManager for scheduled events, like with dumpsys alarm on the command line? Better ideas?

In my experience, the problem is in many cases in the character encoding used in the feed. If the feed is encoded using ISO-8859-1 encoding (which is what CNN top stories appears to use), and you are trying to read it using the default UTF-8 encoding some symbols will come as invalid and break the parser. The only viable solution is to manually detect the encoding before trying to parse and then construct the input stream given to the parser with the correct encoding.

[android-developers] Re: Alarms get lost when upgrading an application
Stefan, thanks for pitching in and shedding some light on it. Also not a deterministic approach, but at least it is not tied to the UI. Anybody else with another apporach? Cheers, Mariano On Sun, Mar 1, 2009 at 4:16 PM, StefanK skyntc...@gmail.com wrote: I noticed the same thing. I looked at the AlarmManger code and it stores its data in in-memory arrays that are not persisted (nor publicly accessible) , even more the pending intents that the AlarmManager refers to are also lost when the device is restarted or the application is uninstalled. (This is actually what happens when you uninstall - it is the pending intent that gets lost not the AlarmManager registration). It appears that the only way to deal with pending alarms is to reschedule them. What I did in my application is to register for 3 global events - in my case Intent.ACTION_TIME_CHANGED (which occurs when the phone time gets updated to some value manually or by syncing with the cell tower), Intent.ACTION_TIMEZONE_CHANGED, and Intent.ACTION_BOOT_COMPLETED. In response to any of the those events I remove all pending alarms and reschedule them again reading the schedules from my own storage. This takes care of the device reboots and when the time zone changes (for example the user takes a plane from one time zone to another). As it turns out if your device is set to auto sync its time from the cell tower (which is the default setting) the autosync occurs many times during the day (my guess is when switching from cell towers to another). Responses to the ACTION_TIME_CHANGED will restore the schedule. This is not an ideal solution but it is good enough for my case. (The AlarmClock application that comes with the Android Source uses a similar approach) Stefan On Feb 28, 10:58 am, Mariano Kamp mariano.k...@gmail.com wrote: Hi, as far as I see scheduled alarms are lost when upgrading an application. As this seems to be an un-install and re-install I can understand what. What is the best way to cope with that? When an application is upgraded it doesn't need to be launched by the user, so it is not the most sensible approach to use the onCreate method of the launcher activity. Is there any other life-cycle event I can tap into? If that is not the case, then I would think a not-too-bad-way of handling this is to hook into the onCreate method on my launch activity, an create a PendingIntent with the NO_CREATE [1] flag and schedule it again with the AlarmManager. That shouldn't result in any change to the existing schedule, if it exists, and should create the schedule when the application is installed for the first time or after an upgrade. It's not elegant, as it expects the user to open the app after upgrading. It's not a major PITA today as the current Market expects the user to upgrade each app by hand and it is not unlikely that the user starts it, but for the future I would expect that the Market makes automatic mass-upgrades possible. Also it is not too nice to handle this logic in the UI. Furthermore it doesn't seem elegant to bother the AlarmManager with a new PendingIntent every time the app is launched. Is there anyway to query the AlarmManager for scheduled events, like with dumpsys alarm on the command line? Better ideas?

I have successfully implemented the Media Player for my apps, but when I tried to use some of the callback methods I ran into a problem. What I'm trying to do is use Media Player in a reusable (library) class. This stand-alone library class (call it MyMediaPlayer) is created by passing the Activity Context to it's constructor. I then use getApplicationContext to avoid any potential memory leaks. My problem is trying to use callbacks. When I implement MediaPlayer.OnPreparedListener in my library class, it doesn't ever get called. To test this further, I created a separate project, that has a single activity, that also implements the OnPreparedListener. In that project, the onPreparedListener is called, and it works. Both are coded this way: (mp = MediaPlayer, and the MyMediaPlayer class implements/overrides OnPreparedListener) mp = MediaPlayer.create(context, resourceId); mp.setOnPreparedListener(this); MediaPlayer.create() calls prepare() internally, so it doesn't seem that useful to set an onPreparedListener after prepare() has already finished. The fact that it works in your Activity is not something you should rely on. It only works in your Activity because the callbacks are posted to the main Looper, and in this case your main loop isn't going to process the callback event until after you've set the listener, even though in reality prepare() has already finished by the time you set the listener. I'm guessing that when you do this in your library, you're doing it from another thread, and so the event is either dropped because that thread doesn't have a Looper, or it is processed in the main Looper before your thread gets around to calling setOnPreparedListener(). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

That did the trick! Thanks! It's a bit complicated... My app is a todo list, and i kind of have a symmetric concept (touch vs. keyboard) there's basically nothing you can't do in either of them. Theoretically there could be an infinity of views, and it would be a little too much overhead to set them all as non-focusable just for this + the way i see it (in my context) using the trackball would be a long way around any existing function.

I thought about that, but the log shows that I acquired the lock and then

Also I would need to use a Thread.join() in the onReceive Method to wait for
the thread to finish, which would lead to a long execution of the

I don't think it's valid to start a Thread in a BroadcastReceiver. The system doesn't know anything about that thread, so it wouldn't know that it's supposed to keep the process hosting it around. My app nanoTweeter does similar background polling and I acquire the WakeLock in the BroadcastReceiver and then start a Service. That service releases the lock when it's done. -- Jon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: How to get auth token (GoogleLoginService?)
I can see why the user's Google credentials are not accessible to just any app. I wouldn't want apps to be able to use my Google credentials unless I specify that it's ok. The minimum requirement would be that access to Google credentials would require a line in the manifest file so the user knows which apps log in to Google. But still, as a user I would want to be able to switch that off. My app just asks for the credentials once. Flickr has a neater way of doing this. If you want acces to your user's Flickr account, you point them to a Flickr page where they can check a checkbox that gives your app permanent access to their account. The nice thing about that is that the user can switch if off, independently of your app, in their Flickr account. Access to a Google account can only be switched off by uninstalling the app, changing your Google password or removing the credentials from the app - if you trust the maker of the app. The worst thing to do is to hand credentials from one site to another without user interference. That's what some Twitter clients do with Twitpic: they log in to Twitpic with your twitter credentials, thus handing your Twitter password to a third party. That's why I don't use Twitpic.

[android-developers] Re: Assuming Developers are Pirates
The whole premise of this discussion is wrong. What has happened is: 1. The developer asked for their application to be copy protected with forward locking. 2. The user is running a phone that is unlocked, so can not do that kind of copy protection. 3. The Market does not allow the user to download the app, because their phone does not support a feature the developer has requested. It has nothing to do with assuming anyone is a pirate, it has to do with doing what the developer has asked.

There is NO image for the adp1 that allows paid OR protected apps (including free-protected and paid-unprotected). The holiday image is for google employees only, on the phones they received instead of a bonus last year. So..yeah.

[android-developers] webview problems when rendering HTML and using loadData
I know that many of you know this already but I am making a post
because I spent 5 hours trying to figure out why loadData was not
working. This does not pop up easily in searches of the mailing list.
TAGS: webview background white android loadData
WebView momentContent =
(WebView) view.findViewById
(R.id.subscription_list_moment_webcontent);
WebSettings wsettings =
momentContent.getSettings();
wsettings.setJavaScriptEnabled(true);
//works great
//momentContent.loadUrl(http://www.momentarynow.com/app/public/
android/info_about.html);
//doesnt work exact same content WHY?
momentContent.loadData(
ResourceUtils.loadResToString(R.raw.content,
mContext),
mimeType,
encoding);
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN
html
head
titleUntitled Document/title
meta http-equiv=Content-Type content=text/html; charset=UTF-8
style type=text/css
!--
.bg {
font-size: x-small;
background-color: #CC6600;
}
--
/style
/head
body class=bg
foobar
/body
/html
unless you use the most simple html possible, like no style sheets,
backgrounds, etc, loadData seems to blow up. The only workaround I
have found is to use loadDataWithBaseURL instead
final String mimeType = text/html;
final String encoding = UTF-8;
//render the html
WebView momentContent =
(WebView)
findViewById(R.id.subscription_list_moment_webcontent);
WebSettings wsettings =
momentContent.getSettings();
wsettings.setJavaScriptEnabled(true);
momentContent.loadDataWithBaseURL(http://fake.com;,
ResourceUtils.loadResToString(
R.raw.content,
getApplicationContext()),
mimeType,
encoding,
http://fake.com;);
oh now it magically works. but my forehead is a bit bruised from
hammering it against the brick wall.
I merely post to help others avoid my fate.

[android-developers] Re: SAXParser fails on some RSS feeds
I just wanted to report that I've tried TagSoup and at first glance it seems to be doing exactly what I want - this is great! Instead of using a SAXParserFactory I'm now using the SAXFactoryImpl class in TagSoup to instantiate a new SAXParser. I will need to look it over a bit more but it just parsed through a copyright symbol without any complaints!!

The only viable solution is to manually detect the encoding before trying to parse and then construct the input stream given to the parser with the correct encoding. This is what I end up doing for BeyondPod in both Windows Mobile and Android platforms and this solved large set of parsing issues. Welcome to the bizarre world of RSS parsing.

[android-developers] Re: How to use proxy server on the g1?
Hello, I've written an application which may help, it allows you to use the browser from behind a proxy server on a WIFI network. Search for the ProxySetting application on the market (its free). At the moment Android only allows proxy information to be used when you are connected to a GPRS/3G network, there's a bug raised about it here: http://code.google.com/p/android/issues/detail?id=1273. The ProxySetting application works around the problem, but unfortunately it's still a bit limited (by Android): It does allow for using the web browser behind a non-authenticated proxy, but apps such as Maps and Youtube don't currently work and there's no way to add a username/ password for the proxy. I'm sure this will be sorted out properly by the Android team, but until then hopefully the ProxySetting app will help. Please let me know if it works or if you have any problems (I've only just posted it on the Market so haven't had any feedback yet). Thanks!

[android-developers] How to get an interface on a service without destroying the service at unbind
My service works exactly the way i want as long as i use start and stop and communicate using intents. However my activity needs to change the state of my service as well as retrieving state information. So i thought it would be nice to broadcast some kind of state_changed event from my service and use a binder interface to pull information from the service or change the services state based on user input. This works fine too. The only problem is that my service gets killed when i unbind it just as the documentation says. Is there any way to keep the service alive but still get an interface to control it directly. My activity offers the user a way to stop the service and the service kills itself anyway after it's work is done but i don't want the service to stop every time the activity is destroyed.

Before starting on the mobile programming world, it is better to gain some basic experience with desktop application programming (JavaSE) because running and debugging is relatively easier, simpler and faster.

[android-developers] Re: How ratio of dp-to-pixel change with the screen density?
Thank you very much for your clear explaination. Now I agree with you that we had better use dip/sp as the dimention unit to design the UI. However when we shall use px/mm/pt? On 3月1日, 下午12时16分, Romain Guy romain...@google.com wrote: Hi, The reason for dip to exist is simple enough. Take for instance the T-Mobile G1. It has a pixel resolution of 320x480 pixels. Now image another device, with the same physical screen size, but more pixels, for instance 640x480. This device would have a higher pixel density than the G1. If you specify, in your application, a button with a width of 100 pixels, it will look at lot smaller on the 640x480 device than on the 320x480 device. Now, if you specify the width of the button to be 100 dip, the button will appear to have exactly the same size on the two devices. You can easily see this happen when you compare the T-Mobile G1 with the Android emulator. Computer monitors usually have low/medium pixel densities. For instance, the monitor I'm using to write this email has a density of about 100 pixels per inch, whereas the G1 has about 180 pixels per inch. This means that when I compare my application on the G1 with my application on the Android emulator on my computer, the version on my computer appears a lot bigger to me. It is very important that you use resolution independent units like dip when you create your UI. This well help make your application run on future Android devices that may or may not have the same pixel density as the G1.

As described inhttp://code.google.com/intl/zh-CN/android/reference/available-resourc..., 1 dip (density-independent pixel) means 1 pixel on a 160 dpi screen. Why does the ratio of dp-to-pixel not necessarily change with the screen density in direct proportion? When the dpi is changed from 160 to 80, how many pixels will 1dp will take? 0.5?

[android-developers] Re: Think twice before turning on the Copy Protection option! -- there's a serious bug in Market
I just had the same issue happen to my application. I decided to disable Copy Protection after reading how useless it was, and now everyone is getting Force Quit errors on Activities with a WebView!!! I have turned Copy Protection back on and added a note to the description saying to uninstall then reinstall. Is this the appropriate course of action? I can't believe this hasn't been fixed yet! (or at least put a warning in the Market Developer Console). :( On Feb 27, 6:31 am, wayne mcfadden- Red Droid waynemcfad...@gmail.com wrote: I'm also having this problem. I have a couple of apps using copy protection though and this is the first one that has run into this problem. I first tried to upload my app via firefox and forgot that that that interface is broken and has been broken for the past 2-3 weeks. So I switched to Safari and finished the upload from there. I'm wondering if this is only a regional problem, the few emails that I've gotten are googlemail accounts which are England and Germany I think. Have you found that? Or any work arounds? Looks like turning off copy protection is a bad idea? Wayne On Feb 26, 12:42 am, mac gr...@czesla.de wrote: That will be the same for my application. I startet with copy protection in the first version. After some people were not able todownloadthe application (another bug with some APN?) I switched off copy protection.

I turned on copy protection on a free app. People started getting crashes. The app starts with a help activity containing a webview. This web view is now throwing an exception trying to access a sqlite webview.db database on it's own thread and crashing. In addition, this help activity only starts up if there are no settings but even upgrades are getting this activity now. It problem extends to other android APIs as well because if I avoid the webview, it still crashes in other APIs. In summary, if you change copy protection for your app: 1. user preferences will be wiped 2. webview willcrash 3. other APIs willcrash Removing copy protection does not help because now I've got some users with and without copy protection and changes in either direction causes the problem.

If you first install an apk unlocked, and then install a locked one, you will get that sqlite exception. also, the old preferences seems to be deletedafterthe locked apk is installed. Another thing is, even installed locked from scratch (uninstall and adb install -l), there are some problems with resources. Our app displays an HTML page when it starts, but now I get Web page not available:file:///android_asset/welcome.html This works fine if it's installed unlocked. This might explain the resource problem that I had before? On Feb 22, 9:18 am, Carter ccjerni...@gmail.com wrote: I can confirm that there is a bug with the forward locking on the Android Market. The problem I've experienced is that users upgrading from an unlocked version of Locale to a locked version of Locale are experiencing acrashwhen opening the app. The failure is that the app can'topenits ContentProvider (a call to SQLiteOpenHelper.getWritableDatabase()fails). As an experiment, I tried wrapping the section in a try-catch and to use a newdatabase filename. My thought was that the old sqlitefilemight be unreadable because of permissions or other problems. This didn't work though. In your apps, you should be able to reproduce this bug by doing a plain old adb install myapp.apk,openthe app on the phone, then do an adb install -l -r myapp.apk. The -l option enables forward- locking. When you re-openthe app of the device, you should see the problem reproduce. This problem also occurs both ways, so users who successfully installed the locked version of the app will see acrash if the next version of the app is unlocked. I've also contacted someone at Google about this, so we'll see what happens. On Feb 21, 4:43 pm, focuser linto...@gmail.com wrote: There's no error whatsoever when that happens.

[android-developers] Re: Assuming Developers are Pirates
Market doesn't stop downloading of applications to devices that don't support copy protection because users with a rooted US G1 firmware are allowed to download the apps (see http://strazzere.com/blog/?p=185). I'm going to play devils advocate here because I can see where many of the posters are coming from; If what's been deployed is a response to developers asking for copy protection and forward locking why was a scheme implemented that couldn't be used on devices which had been sold months before the system was rolled out? JBQ said it was a time constraint, some will say it's because Google assumed that ADP1 users would the extra facilities to crack the copy protection,. My personal view is that it's a side effect of project management and QA failures on the project which have resulted in the deployment of a solution which neither meets developers needs nor does it vastly increase the effort needed to copy and run applications on another device. Al. Dianne Hackborn wrote: The whole premise of this discussion is wrong. What has happened is: 1. The developer asked for their application to be copy protected with forward locking. 2. The user is running a phone that is unlocked, so can not do that kind of copy protection. 3. The Market does not allow the user to download the app, because their phone does not support a feature the developer has requested. It has nothing to do with assuming anyone is a pirate, it has to do with doing what the developer has asked.

So far, google has only assumed their OWN EMPLOYEES are thieves. (Yes, they've said the same restrictions are in the unreleased adp1.1 image, but since its unreleased that could still change..) There is NO image for the adp1 that allows paid OR protected apps (including free-protected and paid-unprotected). The holiday image is for google employees only, on the phones they received instead of a bonus last year. So..yeah. Google has acted to indicate that they believe, given the chance, their employees will steal applications. (Funny, and kinda sad. Although they'd be getting just as much of a roasting if they had gone the other way with it.)

The thing that drew me to the android platform was the fact that it had such a lower barrier to entry. I can't afford to have two phone plans going. The idea of investing $425 to allow me to have one device to both develop for and use for my day to day life was very attractive. However, Google's recent assumption that developers will pirate drm'd software simply because they can is ridiculous. If someone wanted to pirate software, they'd simply open a t-mobile account, unlock the phone, and save $300+.
